Remarkable bone mineral density increases on teriparatide in patients with glucocorticoid-induced osteoporosis and Crohn's disease

Ko-Wu Kuo Danny , To Kenny , Kendler David

Crohn’s disease often results in abnormalities in bone strength, and ultimately increases the risk of fragility fracture. Up to 55% of patients with Crohn’s disease have bone mineral density in the osteopenia range up to 50% of osteoporosis. Glucocorticoid is frequently used in the treatment of Crohn’s disease and is associated with osteoporosis and increased fracture risk. It has been reported that osteoporotic fractures in patients with Crohn’s disease ar...

Denosumab therapy results in a high frequency of responders by bone mineral density in both treatment-naïve patients and patients switching therapies

Almohaya Mohammed , Liu Angela , Kendler David

Clinical trials suggest that denosumab (DEN) therapy results in greater increases in bone mineral density (BMD) in treatment-naive patients than in patients switched from bisphosphonates.We retrospectively reviewed charts of all patients treated with DEN at an osteoporosis referral centre in Vancouver, Canada including all patients treated with DEN 60 mg SC every 6 months for 1 year or more, and in whom baseline and follow-up BMDs were available. BMD was...

Estimation of vertebral and femoral strength during the first three years of denosumab therapy using an alternative smooth non-linear finite element methodology

Denosumab subcutaneous administration every 6 months reduced the incidence of new fractures in postmenopausal women with osteoporosis by 68% at the spine and 40% at the hip over 36 months compared with placebo in the FREEDOM study (Cummings et al., NEJM, 2009:361:756). This efficacy was supported by differential improvements from baseline in vertebral and femoral strength at 36 months (18.2 and 8.6%, respectively) estimated by an established voxel-based finit...

Denosumab treatment in women with osteoporosis reduces hip cortical porosity

Zebaze Roger M , Libanati Cesar , McClung Michael R , Zanchetta Jose R , Kendler David L , Hoiseth Arne , Wang Andrea , Ghasem-Zadeh Ali , Seeman Ego

Bone strength is influenced by cortical thickness, area, mass and porosity, all of which contribute to nonvertebral fracture risk. Cortical porosity is one parameter of structural decay associated with bone fragility. This is caused by unbalanced and accelerated remodelling of Haversian units which enlarge, coalesce and fragment the cortex. Antiresorptive therapies will limit progression of cortical porosity; reducing existing porosity would be a goal for those already at incr...

Bone histology and histomorphometry: effects of 5 years of denosumab in the FREEDOM Extension

DMAb increases BMD and reduces bone resorption and risk of vertebral, nonvertebral and hip fractures in women with PMO. Transiliac crest bone biopsies in 47 subjects treated with DMAb for 1–3 years showed reduced bone turnover vs 45 Pbo-treated subjects, which reversed on treatment cessation. Since bone turnover reduction is sustained and fracture incidence low over 6 years’ DMAb treatment, we evaluated DMAb’s effects on tissue-level remodelling in the FREEDOM E...
